Great Lakes | YPGG - Why Green?

CHICAGO - The U.S. Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency (MPCA) today announced a $10.1 million Great Lakes cleanup in Duluth, Minnesota. The projects will focus on the Minnesota Slip near the downtown Duluth waterfront and Slips 3 and C in the Duluth Harbor. This is part of a larger effort to restore the St. Louis River Area of Concern through the Great Lakes Restoration Initiative.

“The Duluth slip cleanups demonstrate the commitment of EPA’s Great Lakes Restoration Initiative to clean up legacy pollution, working in cooperation with industries, states, and local agencies,” said EPA Regional Administrator Cathy Stepp.

“These cleanups, and really the entire St. Louis River Area of Concern project, are a great example of how local-state-federal partnership and cooperation is supposed to work to protect the environment and human health,” said MPCA Commissioner John Linc Stine.

The three projects will result in the remediation of approximately 154,000 cubic yards of polluted sediment contaminated with heavy metals, dioxins, PCBs, and polyaromatic hydrocarbons, or PAHs. The U.S. Army Corps of Engineers is assisting the two agencies.

In October and November of this year, the Minnesota Slip cleanup will result in the remediation of about 37,000 cubic yards of contaminated sediment. Project activities include moving 2,500 cubic yards of mud within the slip to level the slip bottom and allow for its continued use. Contaminated sediment will be capped with 2 feet of dredged material from clean areas of the harbor along with a layer of stone. The cap will isolate contaminants and protect against damage from boat traffic.

The project will cost $6.5 million, including in-kind contributions of $3.6 million from MPCA in partnership with the city of Duluth and Duluth Entertainment Convention Center. These in-kind contributions will help fund required dock wall stabilization and allow for the temporary relocation of the SS William A. Irvin. The retired freighter is scheduled to move this September and return to the Minnesota Slip next spring.

Slips 3 and C will undergo a $3.5 million cleanup this fall. More than 116,000 cubic yards of contaminated sediment will be capped with approximately 2 feet of dredged material from clean areas of the harbor along with a layer of stone.

The St. Louis River and Bay is one of 27 U.S. areas of concern targeted for cleanup under the Great Lakes Restoration Initiative and the Great Lakes Water Quality Agreement. Since 2016, more than $125 million has been committed to restore the AOC, including the $75 million Spirit Lake cleanup of the former Duluth Works site announced last week.

CHICAGO - The U.S. Environmental Protection Agency (EPA) and U.S. Steel Corp. announced on 08/29/2018 an agreement to undertake a $75 million cleanup and restoration project at the former Duluth Works site on the St. Louis River at Spirit Lake in Duluth, Minnesota. This is part of a larger effort to restore the St. Louis River Area of Concern through the Great Lakes Restoration Initiative.

“Today’s $75 million restoration project with U.S. Steel shows that public-private partnerships can deliver results, in this case, a major step forward in restoring the St. Louis River AOC,” said EPA Regional Administrator Cathy Stepp.

“We are excited to continue our successful partnership with EPA to address legacy impacts at our former Duluth Works. By responsibly managing impacted sediments, we will create new desirable habitat in the estuary,” said U.S. Steel President and CEO David Burritt.

The planned Spirit Lake project includes dredging 700,000 cubic yards of contaminated sediment and building three on-site confined disposal facilities. The plan also calls for constructing an engineered cap over 100 acres of estuary sediment and creating a new 30-acre sheltered bay. The design work is expected to be finished in December 2018 and is being done in close coordination with the Minnesota Pollution Control Agency.

Background

The Spirit Lake project is being completed under the authority of EPA’s Great Lakes Legacy Act, with U.S. Steel providing 55 percent of the total project cost and EPA providing the remaining 45 percent. Construction is expected to begin in 2019.

The partnership at the site between EPA and U.S. Steel began in 2011 when U.S. Steel approached EPA with a proposal to enroll the site in the Great Lakes Legacy Act program and complete a remedial investigation. The successful completion of the collaborative investigation led to additional cost-share agreements to complete a feasibility study and the current remedial design.
